“…Heat is essential for the curing, sintering and drying of clay-based construction products in order to gain an adequate strength for civil engineering applications [24][25][26]. However, the use of conventional heating methods is relatively slow due to the low thermal conductivity of claybased construction materials and the slow rate of heat transfer from their surface to their core [26,27].…”

“…However, the use of conventional heating methods is relatively slow due to the low thermal conductivity of claybased construction materials and the slow rate of heat transfer from their surface to their core [26,27]. In addition, researchers have identified the disadvantages associated with conventional heating technologies such as high-energy consumption, long processing times, high processing temperatures and the associated negative environmental impacts [24,26,28,29].…”

Sustainability in the manufacture of different construction materials raises many important issues. Nowadays, there is increasing demand for such materials to be produced using environmentally friendly, low energy consuming production methods. This paper presents a review of the current research relating to the use of various production techniques for claybased construction materials. The techniques which will be reviewed are: blending and stabilising, alkali activation (geopolymerisation) and the use of microwave heating as an innovative sintering, curing and drying method. The advantages and disadvantages of each technique will be discussed. Additionally, a comparison between the environmental and economic aspects of the studied production techniques along with some suggestions to improve the sustainability of different production techniques will be discussed.

“…The microwave processing technique has several advantages like: rapid heating, penetrating radiation, obtaining more uniform microstructure and hence higher density. Moreover, this technique is inherently dry and fumeless process, which means environmentally clean, therefore it is also known as clean processing technique [11,12]. In the microwave processing of ceramics, electromagnetic waves interact with the ceramic materials, leading to volumetric heating.…”

“…Microwave heating also has the potential for energy and cost savings when compared with conventional heating processes. Besides that, nearly theoretical density and uniform grains, which in turn improves physical properties of ceramics, can be achieved in microwave processed ceramic samples [11,12]. Therefore, the synthesis of BFN and CCTO ceramic samples by microwave assisted solgel processing technique can help obtaining dense and uniform grain size with pore free microstructures, which can improve the material's electrical properties.…”

Ba(Fe 1/2 Nb 1/2)O 3 (BFN) and CaCu 3 Ti 4 O 12 (CCTO) ceramic powders were synthesized by microwave assisted sol-gel synthesis technique and sintered at 1100°C and 1000°C, respectively. Calcination and sintering processes were carried out in a microwave furnace. Dielectric constant (ε r) ∼2450 and dielectric loss (tan δ) ∼0.5 at frequency of 1 kHz and 20°C were observed for the BFN ceramic samples. Higher value of ε r ∼ 3600 and lower value of tan δ ∼ 0.07 at frequency of 1 kHz and in 20-60°C temperature range for the CCTO ceramic samples suggested its utility for MLC applications. Sharp decrease of ε r and sharp increase of tan δ at higher frequencies of BFN ceramic samples indicated the presence of Debye like relaxation.

In long run, the ceramic industry's environmental footprint is a serious issue for its survival. This study focused on the substitution of clay (kaolin) by incinerated bottom ash, which is generated from reppi waste to energy power plants for ceramic wall tile production. Dry pressed ceramic wall tile samples were prepared by adding bottom ash from 0 to 60 wt% with clay (kaolin). The sample was analyzed after sintered at 1110°C for the residence time of 45 min by testing water absorption, breaking strength, and flexural strength. The water absorption is greater than 10%, and higher flexural strength of 24.83 MPa was obtained for the clay with 30 wt% incinerated bottom ash addition. Encouraging test result has been obtained on using up to 30% of incineration bottom ash in the manufacturing of dry pressed ceramic wall tile to substitute clay (kaolin).
